Wilhelm Tempel discovered NGC 4289 = T I-42 in 1877. His position and description (BD +4°2606 follows by 12 sec of time) matches UGC 7403.

400/500mm - 18" (5/8/04): very faint, thin edge-on 5:1 N-S, 1.0'x0.2', very weak concentration. This delicate sliver required some care in first acquiring. A mag 8.4 star (HD 107473) just 3.1' E detracts from viewing. Located 47' SSW of M61.
